Crohn ileitis and sacroiliitis


This case illustrates circumferential mural thickening and inflammation in the distal ileum, associated with free fluid in the pelvis, in keeping with active ileitis related to Crohn's disease.

Changes of bilateral sacroiliitis and lower thoracic spine spondylitis are consistent with enteropathic arthritis, which is a seronegative chronic inflammatory arthritis associated with the occurrence of an inflammatory bowel disease.
